Specific embodiment
Below the present invention is described in further detail, but embodiments of the present invention not limited to this.
As shown in Figures 1 to 3, water intaking structure includes: water intaking box culvert 100 and flume 200.
The vertical type box culvert that water intaking box culvert 100 is made for armored concrete.Water intaking box culvert 100 is towards water sources such as rivers,lakes and seas
One side be water intaking face 101 (in the present embodiment, the water source of water intaking structure is seawater), be provided with surge chamber in water intaking box culvert 100
110, surge chamber 110 be rectangular shape, the inwall near water intaking face 101 side for the surge chamber 110 be front, with vis-a-vis
Side is provided with the opening 111 of surge chamber 110, and flume 200 is provided with channel 210, and the entrance width of channel 210 is more than outlet
212 width, the both sides inwall of channel 210 is from the import of channel 210 to exporting 212 rounding ofves.The import of channel 210 and buffering
The opening 111 of room 110 docks, and channel 210 is connected with surge chamber 110.
It is additionally provided with least two water intaking passages, water intaking passage is provided with intake on water intaking face 101 in water intaking box culvert 100.
Water intaking passage includes just fetch water passage 121 and side draw aquaporin 122.Some (at least one) passage 121 of just fetching water is arranged at
Near the position at water intaking box culvert 100 middle part, passage 121 of just fetching water is connected with surge chamber 110 from the front of surge chamber 110.Article four,
Side draw aquaporin 122 is divided into two groups, is respectively arranged on water intaking box culvert 100 near the position at both sides edge, side draw aquaporin 122 is postponed
The side rushing room 110 is connected with surge chamber 110, and side draw aquaporin 122 includes being sequentially connected from intake to surge chamber 110 direction
Outer section, bending section, inner segment, outer section is arranged side by side with passage 121 of just fetching water, and inner segment is by bending section towards to surge chamber 110
Side.Side draw aquaporin 122 is connected with surge chamber 110 from side, and the inside setting water intaking making full use of water intaking box culvert 100 is logical
Road, in the case of the water intaking area identical of intake, the overall width of the opening 111 width ratio water intaking box culvert 100 of surge chamber 110
Degree is little, and the import of channel 210 is directly docked with the opening 111 of surge chamber 110, the entrance width of channel 210 and surge chamber 110
Opening 111 width matches, overall across water intaking box culvert 100 without making channel 210, the construction area of minimizing flume 200,
Reduces cost, more environment-friendly.
When taking water, seawater enters surge chamber 110 from intake, subsequently into channel 210, exports 212 via channel 210
The condensing plant of supply power plant uses, and the hot water that power plant's condensing plant discharges can also reversely enter marine.Water intaking is interchannel
Partition wall can also serve as diversion pier, so that flow rate of water flow is evenly distributed, and reduces the water intaking disturbance to upper strata or low layer water body for the structure, and
Reduce the volume to fish to inhale.
The both sides canal wall of flume 200 is usually to be piled up using the finely divided material of sandstone or stone and makes, structure loosely,
There is the risk being lost by current scour, for this reason, being to avoid the water impact flowing out from water intaking box culvert 100, diversion in prior art
The width of channel 210 import of canal 200 is more than the width of water intaking box culvert 100, and the canal wall of flume 200 and reinforcement walls 300
The water intaking face of extending to 101 place face, occupation of land is huge, unfriendly to ecological environment, cost is high.In the present embodiment, water is from intake
By fetching water, passage enters surge chamber 110, is then caused in power plant by flume 200, by the buffering of surge chamber 110, introduces
Current will not directly impact flume 200, flume 200 is directly docked with the opening 111 of surge chamber 110, without extension
To water source, reduce the construction area of length, the reduces cost of flume 200.
The inwall of channel is the round and smooth arc tangent with water intaking box culvert 100 back side (i.e. surge chamber 110 opening 111 place face)
Shape, gently flows in channel 210 beneficial to water is smooth.Side draw aquaporin 122 is provided with bending section, opens reducing surge chamber 110
While mouth 111 width, the center flowing to surge chamber 110 of the current of entrance surge chamber 110 can be made, without just rushing over the ground
Hit the inwall of channel 210, reduce channel 210 inwall and washed away by current.Meanwhile, arrange at the cross section of flume 200
There are reinforcement walls 300, support, channel 210 inwall of flume 200 and water intaking box culvert 100 can be consolidated for the offer of piling up of building stones
The back side is tangent, and the cross section of canal wall is located at the outside of the side of canal wall, in the joint of flume 200 and water intaking box culvert 100, draws
The width of water channel 200 is less than the width of water intaking box culvert 100, and the outside of the canal wall of flume 200 is outer with respect to water intaking box culvert 100
Wall is inwardly made a concession composition and is made a concession recessed, and reinforcement walls 300 are recessed interior located at making a concession, and flume 200 and the total width of reinforcement walls 300 are not more than
The width of water intaking box culvert 100 entirety, and, the width of the maximum of flume 200 is less than or equal to the front of water intaking box culvert 100
Width, saves building and takes up an area, environmentally friendly, reduces cost.
As shown in 4,5 figures, water intaking box culvert 100 also includes load-carrying portion 130, and the actual face of putting with box culvert 100 of fetching water is
Datum level, located at the top of water intaking box culvert 100, water intaking passage is located at the bottom of water intaking box culvert 100, load-carrying portion 130 in load-carrying portion 130
It is located at the top of water intaking passage.Load-carrying portion 130 is provided with and takes up groove, takes up to fill out in groove and sets sandstone or other weights, plays suppression steady
Admittedly the effect of water intaking box culvert 100.The top high flow surface throughout the year of water intaking box culvert 100, the upper limb absolute altitude of intake is less than or equal to
3m below the water intaking on-site mean low-water of structure, can avoid the higher seawater of surface temperature, avoid sucking seawater surface
The debris of floating.And, the lower edge absolute altitude of intake is greater than or equal to the top 1m in the water intaking on-site seabed of structure.So,
The higher seawater of surface temperature and the more seawater of bottom silt can be avoided, take middle level low temperature seawater, unit can be significantly reduced
Design back-pressure, improves unit efficiency, mitigates the live load of filter plant.
Each technical characteristic of above example can arbitrarily be combined, for making description succinct, not to above-described embodiment
In all possible combination of each technical characteristic be all described, as long as however, the combination of these technical characteristics does not have lance
Shield, is all considered to be the scope of this specification record.
Above example only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but can not
Therefore it is construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art,
On the premise of present inventive concept, some deformation can also be made and improve, these broadly fall into protection scope of the present invention.
Therefore, the protection domain of patent of the present invention should be defined by claims.
